ablated by the X-rays produced by the Hohlraum wall upon irradiation by lasers. Due to Newton's third law, the inner portion of the fuel capsule implodes, causing the D-T fuel to be supercompressed, activating a nuclear fusion reaction]].

The radiation source (e.g., laser) is pointed at the interior of the Hohlraum rather than at the fuel capsule itself. The Hohlraum absorbs and re-radiates
